"Are you suggesting that Israel should not have responded?"
I'm saying they should explain how a group of heavily armed enemies approached their border in tractors and then floated into Israel, via paragliders, without anyone knowing.
It seems to me like the multi billion dollar defence/surveillance system either wasn't delivering bang for buck or, alternatively, Israel was looking for a reason to activate some revenge slaughter. With these paranoid psychopaths, I'm firmly of the belief it was the latter.
